Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Self-Presentation: Self-Monitoring and Self-Handicapping

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Binge Eating Disorders

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Stress Prevention and Stress Management Techniques IV

Stress Prevention and Stress Management Techniques IV

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Hypothesis Test for Test of Independence

Hypothesis Test for Test of Independence

The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

CNS Depressants: Alcohol and Nicotine

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Summary

High-intensity drinking (HID) in young adults is linked to specific sociodemographics and risk factors. Understanding these unique factors is crucial for developing targeted interventions for high-risk drinkers.

Area of Science:

Psychology
Public Health
Substance Use Research

Background:

Interventions for high-risk alcohol use require understanding factors differentiating drinking intensity.
High-intensity drinking (HID) represents a significant public health concern among young adults.

Purpose of the Study:

To identify sociodemographic and risk factors distinguishing high-intensity drinking (HID) from other drinking levels in young adults.
To provide evidence for tailoring interventions for the highest-risk young adult drinkers.

Main Methods:

Analysis of cross-sectional data from the 2019 Monitoring the Future study, focusing on participants reporting past 30-day alcohol use.
Examination of bivariate associations between drinking intensity levels (moderate, binge-only, HID) and various sociodemographic, risk, and consequence variables.

Main Results:

Binge-drinking norms, specific drinking motives, nicotine vaping, and certain protective behavioral strategies were associated with all drinking intensity levels.
Unique risk factors for HID included sex, college attendance, employment, HID norms, harm reduction strategies, family history of alcohol problems, other substance use, and depression symptoms.

Conclusions:

Sociodemographic factors and specific risk profiles differentiate young adult drinking intensity, including high-intensity drinking (HID).
Findings support the adaptation of interventions to address the unique needs of young adults engaging in HID.
